   The Calo tester, also known as a ball crater or coating thickness tester, is a simple and inexpensive piece of equipment used to measure the thickness of coatings.Coatings with thicknesses typically between 0.1 to 50 micrometres, such as Physical Vapor Deposition (PVD) coatings or Chemical Vapor Deposition (CVD) coatings, are used in many industries to improve the surface properties of tools ...

6. Cupping tester - Wikipedia
